VISIA AF™ VR Model DVAB1D1 - 1

Product specifications Physical characteristics Volumea Surface area of device can Materials in contact with human tissued Titanium, polyurethane, silicone rubber Battery chemistry Hybrid CFx lithium/silver vanadium oxide Volume with connector ports unplugged. Grommets may protrude slightly beyond the can surface. c The radiopaque ID and Medtronic radiopaque identifier can be viewed in a fluoroscopic image of the device. d These materials have been successfully tested for the ability to avoid biological incompatibility. The device does not produce an injurious temperature in the surrounding tissue during normal operation. a Replacement indicators < 2.73 V on 3 consecutive Recommended Replacement daily automatic Time (RRT) measurements End of Service (EOS) Maximum energy levels and typical full energy charge times Maximum programmed energy Maximum delivered energya,b 36 J Maximum stored energyc Typical charge time at Beginning of Service (BOS)d Typical charge time at Recommended Replacement Time (RRT)d a Energy delivered at connector block into a 50 Ω load. For 35 J programmed energy, delivered energy exceeds 35 J. c Energy stored at charge end on capacitor. d Charge time during a nonwireless telemetry session may be slightly higher. b § AF Diagnostics § PhysioCurve™ Design § SmartShock™ 2.0 Technology § OptiVol™ 2.0 Fluid Status Monitoring § Complete Capture Management

Device parameters RV Lead Noise Timeout AF detection parameters Parameter Least sensitive; Less sensitive; Balanced sensitivity ; More sensitive; Most sensitive Ectopy Rejection Episodes ≥ 6 min ; Episiodes ≥ 10 min; Episodes ≥ 20 min; Episodes ≥ 30 min; Episodes ≥ 60 min Programmable values The measured intervals are truncated to a 10 ms multiple (for example, 457 ms becomes 450 ms). The device uses this truncated interval value when applying the programmed criteria and calculating interval averages. b The Wavelet feature is automatically set to On when VF Detection is set to On. c This...
